Sammanfattning

Abstract—The all spectrum absorption efficiency appears in
the physical bounds on antennas expressed in the polarizability
dyadics. Here, it is shown that this generalized absorption
efficiency is close to 1/2 for small idealized dipole antennas and
for antennas with a dominant resonance in their absorption. Also,
the usefulness of this parameter is analyzed for estimation of
antenna performance. The results are illustrated with numerical
data for several antennas.
